Answer: AExplanation:Fault-tolerantdesign is a design that enables a system to continue its intended operation, possibly at a reduced level, rather than failing completely, when some part of the system fails. The term is most commonly used to describe computer-based systems designed to continue more or less fully operational with, perhaps, a reduction in throughput or an increase in response time in the event of some partial failure

QUESTION 113A technician notices a newly installed CAT5 cable is longer than the standard maximum length. Which of the following problems would this MOST likely cause?

A. Split cableB. EMIC. DB lossD. Crosstalk

Answer: CExplanation: The maximum length for a cable segment is 100 m per TIA/EIA 568-5-A. If longer runs are required, the use of active hardware such as a repeater or switch is necessary. The specifications for 10BASE-T networking specify a 100metre length between active devices. This allows for 90metres of solid-core permanent wiring, two connectors and two stranded patch cables of 5metres, one at each end.

QUESTION 116Which of the following 802.11 standards transmits the signals the GREATEST distance?

QUESTION 117Which of the following fiber types is MOST often used indoors?

A. PlenumB. Modal conditioningC. MultimodeD. Singlemode

Answer: CExplanation: Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Typical multimode links have data rates of 10 Mbit/s to 10 Gbit/s over link lengths of up to 600 meters (2000 feet) and 10 Gbit/s for 300m (1000 feet) — more than sufficient for the majority of premises applications.

A. CNAMEB. PTRC. MXD. A

Answer: CExplanation:Amail exchanger record(MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient’s domain, and a preference value used to prioritize mail delivery if multiple mail servers are available.

QUESTION 119Which of the following TCP ports are used by FTP? (Select TWO).

A. 20B. 21C. 22D. 23E. 25F. 80

Answer: ABExplanation:FTP uses two ports by default: 21 for sending commands, and 20 for sending data. For instance if you said “FTP <ServerName>” it would make the attempt using port 21. If the session was established, port 20 would be using for the data. Note: These are the default ports which is what Iassume you were asking. A server administrator can however configure FTP to use whatever port he defines.

QUESTION 120Which of the following protocols is MOST commonly used for the transfer of router configuration files?

A. SSLB. TFTPC. DNSD. IMAP

Answer: BExplanation:Trivial File Transfer Protocol(TFTP) is a file transfer protocol notable for its simplicity. It is generally used for automated transfer of configuration or boot files between machines in a local environment. Compared to FTP, TFTP is extremely limited, providing no authentication, and is rarely used interactively by a user.
